Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricant pumps are complex and require external housings to absorb forces between the eccentric arrangement and pump elements, leading to tolerance issues and increased manufacturing costs.
Innovation Solution
A lubricant pump design featuring a central base plate that serves as a bearing and mounting unit for the pump element, allowing direct absorption of forces and enabling modular construction with precise positioning, potentially using plastic housings and additive manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If external housings are used to absorb forces between eccentric arrangement and pump elements, then structural stability is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent merges the housing function with the base plate by integrating force absorption capabilities directly into the base plate structure. The base plate is designed to absorb forces occurring between the eccentric arrangement and pump elements, eliminating the need for separate external housings and reducing overall device complexity while maintaining structural stability.
Solution Approach 2:
The base plate is designed to perform multiple functions simultaneously: it serves as a mounting surface for the eccentric arrangement, provides structural support, and absorbs forces between moving components. This multi-functional design replaces what would traditionally require separate housing components, reducing device complexity without compromising stability.
2Ease of manufacture
If multiple individual elements are assembled with conventional methods, then manufacturing flexibility is improved, but tolerance accumulation increases and manufacturing precision decreases
Solution Approach 1:
The patent segments the pump into a modular assembly unit that can be manufactured separately and then integrated into the overall system. This assembly unit includes the base plate, eccentric arrangement, and pump elements pre-positioned relative to each other, allowing precise manufacturing of the module while maintaining flexibility in system-level assembly and configuration.
3Strength
If conventional housing materials and designs are used, then structural strength is improved, but manufacturing costs and weight increase
Solution Approach 1:
The patent changes the material parameters of the base plate by using plastic or composite materials instead of traditional metal housings. The base plate is designed with appropriate thickness and structural features to absorb forces and provide structural strength while being manufactured from lighter, more cost-effective materials through processes like injection molding or additive manufacturing.
